Abstract:
Integrating intermittent non-conventional renewable
energy sources such as wind and solar into power systems
presents unique challenges for its operation. To address this,
effective frequency control mechanisms are crucial. This study
presents a comprehensive analysis investigating the performance
of hydro and steam, in a non-conventional renewable integrated
power system. The analysis aimed to enhance power system
stability through the collective operation of wind and solar
power plants of varying capacities, while maintaining a stable
frequency. In addition, the study investigated the maximum
penetration level of these resources under different contingencies.
Preliminary results indicate that the hydro turbine exhibits a
longer settling time and higher steady-state error compared to its
steam turbine counterpart. Using a 12 bus test system simulated
in PSCAD software, this research provides valuable insights into
turbine performance and the feasibility of integrating renewable
resources, aiding in the improvement of power system stability.
